Document Type and Number:
Japanese Patent JP3871783
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid the generation of a defective caused by abnormality in polishing of a game medium.
SOLUTION: Under a lattice part 105, a recovering pipe 13 is connected through a recovering hopper 12. Above the recovering pipe 13, a first proximity switch 17 is disposed, and the first proximity switch 17 detects if polishing material passing (or dropping) exists or not to supply a detection signal of it to a controller 6. In a polishing material containing tank 14, a second proximity switch 19 is disposed, and the second proximity switch 19 constantly detects the polishing material stored to supply a detection signal of it to the controller 6 in a correct condition. The controller 6 controls rotation of springs 2, 7 through motors 4, 9 based on the signals from the switches 17, 19.
